IMPROVEMENT IN CULTlVATlNG-HARROWS.

Specification formingpart of Letters Patent No. 30,767, dated November 27, 1860.

To all whom it may concern:

Be it known that I, JOSEPH SLocUM, of Syracuse, inthe county of Onondaga and State of New York, have invented certain new and useful Improvements in Cultivating-Barrows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ot' the same, reference being had to the accompanyingdrawings, in whichi Figure l represents a perspective view of saidharrow. Fig. 2 represents adetached view, hereinafter to be referred to.

My invention relates to the arrangement of the several parts of the frame of a barrow by which they can be adjusted in such a manner as that said harrow may be used either for cultivating purposes and converted into a machine for digging potatoes.

To enable others skilled in the art to make and luse my invention, I will proceed to describe its construction and operation.

The center beam/of my harrow is made of two sections, A and B, which are connected to each other by an arched iron brace, I, the object of which will be explained hereinafter. The side pieces, C, of the frame are hinged to the front end ofthe center piece, A, bymeans of the plate N, which is secured to said beam by means of the bolt 4, and to which the side pieces, O, are secured by means of the bolt 3. The rear ends of the side pieces, C, are connected to the center beam, B, hy means ofthe iron braces T, which also serve the purpose of spreading or contracting saidsides, they having adjusting-holes cnear their ends, into which the bolt d may be inserted,by which the braces T are secured to the beam B. y

The cultivator-teeth b are secured to the side pieces, C, and the tooth U is secured to the center beam, and they constitute a cultivator'which is adaptable t'or the cultivation of various crops, as its frame can be spread or contracted at pleasure. It is desirable to use in addition .to these cultivator-teeth a barrow for cultivating. In that case I apply the frame-pieces D, which are provided with harrow-teeth a, by securing them to the plate O by means of the bolts l, said plate being fastened to the beam B lby means of the bolt 2. The outer ends of the frame-pieces D are secured to the braces T by means of the bolts f.

When this cnltivator is to be used for digging potatoes the cross-beam E is secured to the top of1 the side peces, C, by means of the screws g, as represented in Fig. l. The plate G, to which the fingers H are secured, is permanently connected to the cross-beam E, and said fingers, when the machine is drawn over the field, enter the soil, which has been previously loosened by the lcultivator-teeth, and dig up the potatoes, the loosened earth passing through between the fingers H, while the potatoes are rolled out by the ngers'and remain on the top of the soil. The object in using the arched iron brace I in front ot' the potatodigger is to aiford ample room to the potatoes, straw, stalks, orother matters which lodge in front of the fingers H, and which would lhe packed closely together and choke up the spaces between the fingers H if the connection between the beams A and B were a straight one orifa single beam were used in their places.

The shaft of .the rollers or wheels L, which supports the machine when used t'or cultivating, is supported by the bracket K, which is secured to the brace I by means of the bolts 7, and may be adjustable thereon; but in digging potatoes said shaft is set farther'toward the frontend of the machine and on an axle long enough to straddle the rows of potatoes, and this bearing can also be adjusted so as to raise or lower the wheels for the purpose, of causing the cnltivator-teeth and the lingers H to penetrate the ground to any desired depth. The plate M, which is secured to the front end ot' the machine, is serrated at its lower edge and cuts oft' the stalks and weeds and forces them aside when the machine is drawn over the field, and thus prevents them from accumulating in a heap in front ofthe tingers H. This plate can be set higher or lower, as the screws h by which it is secnred'to the side pieces, C, pass through the slots 5, which thus permit ot' the necessary adjustments.

Instead of using a plate with one set of tines 'or lingers H, I may use a plate, Q, with two sets ot' tines, It S, which latter arevset in alternate positions, so that each of :the tines S will bein the center tine ofthe spaces between two of the tinesA R. The plate Q is secured to a separate cross-beam, F, which is secured t0 the sides C in a similar manner as the beam E is secured thereto.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patenis-y i A l A cultivating-barrow composed ot" the two frames C D, furnished with suitable teeth or plows, the side pieces of which frames are vor contracted at their rear ends, and' which are united by a center beam, A I B, composed partially of wood and partially of an arched iron bar, and supported on a pair of wheels, the whole beingrv arranged to operate in the manner and for the purpose herein set forth and represented.
